The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability.
Above 60 °C the value of P

derates linearly with 5.5 mW/K.
